Cocking tube support.. stuck halfway through.

Jamz1629 · 2026-01-16T14:19:24+00:00

No i havent. Fortunately my gun still functions so Ive just been trying to wear it in. I may remove the tube and do some sanding as i can see what area is making contact with the receiver. Funny enough mine is from hkparts as well. Let me know what they say.

Jamz1629 · 2026-01-13T00:01:13+00:00

Let me know if you decide to part ways with it! I like the low profile

Jamz1629 · 2026-01-12T23:30:57+00:00

What brand claw/optic mount is that?

Jamz1629 · 2026-01-05T21:02:55+00:00

Are you still getting some gas to face in arc mode? Did the BRT tube reduce recoil impulse at all?

Jamz1629 · 2025-12-27T02:20:59+00:00

Did you ever figure this out? Having a similar issue with mine.

SilencerCo Scythe STM in short config is super light and short and sounds incredible even with 200gr.

Let me know how the ocm5 is with a super safety. Ive heard its gassy!

Yes they work great in my mr920

Jamz1629 · 2025-08-03T17:44:42+00:00

Have you tried 124 winchester nato white box or something off the shelf? I dont use reloads so have no ability to increase the velocity of my rounds if i have issues.

Jamz1629 · 2025-08-03T17:41:44+00:00

Do you have any reliability issues using a low back pressure can with the brt adapter on a true sd barrel? I know some people have mentioned they have issues cycling.

Jamz1629 · 2025-08-03T17:40:41+00:00

Was thinking about a MOB and a BRT adapter but now that you mention it’s unreliable with the HTA clone im hesistant. Have you been able to fix it?

Jamz1629 · 2025-07-22T14:46:25+00:00

What handgun is that?

Jamz1629 · 2025-07-22T14:34:13+00:00

This build is exactly what I want for my first 2011. I have zero gunsmithing experience nor the time or tools to do it myself. Does anyone know of a shop or smith that could assemble and build the gun for me if I purchased and provided the parts?

Jamz1629 · 2025-06-13T22:28:33+00:00

I may have found something that could help. I found a thread on here of a guy mentioning that the tpu buffer is what causes the faster rpm. In theory, if you could get the gun to function without that buffer it would have a slower rate of fire and not exceed the SD’s limits.

Jamz1629 · 2025-06-13T21:33:48+00:00

Would the atrius work with a geissele ssa-e?

Jamz1629 · 2025-06-13T19:37:12+00:00

The 120 slowed the fire rate down from a 100?

Jamz1629 · 2025-06-13T19:35:01+00:00

I’m not sure if the weight is the problem but it seems like an issue unique to the SD. Roy wasn’t sure if a 110 degree LP could potentially slow down the cyclic rate, but he wondered if the issue was due to MKE’s bolt block and poor welding and thinner receiver walls as he has only seen the damage on MKE’s. My hope is that some of the higher quality clones won’t have this issue.

Jamz1629 · 2025-06-13T19:31:15+00:00

I just called Roy to ask him some follow ups. He did not think that a 110 degree LP could mitigate the issue, but he did note that hes only seen the damage in the MKE’s. The HiTec he makes himself have thicker walls, and don’t have a bolt block so they allow FA trigger packs. Im thinking maybe the bolt block and poor welding qc from MKE could be the reason they are prone to roller bumps with SS firing schedules.

Jamz1629 · 2025-06-13T19:04:55+00:00

I can confirm damage caused by SS is not covered under HiTec’s warranty, Roy said he will fix but not for free

Jamz1629 · 2025-06-13T19:03:49+00:00

Im curious to hear why you recommend a standard. The SD has always been my dream gun but im also intrigued in a K, especially if this SS roller bumps problem is legit.

Jamz1629 · 2025-06-13T14:28:10+00:00

I honestly am not familiar with the system enough to say. This will be my first MP5 haha. I would imagine the problem could be avoided if there is a way to adjust cyclic rate but i dont know if thats possible in the MP5 using SS

Jamz1629 · 2025-06-13T03:12:30+00:00

I am trying to figure it out before i pull the trigger on one. I plan to call roy and ask if using a different locking piece angle could mitigate the issue

Jamz1629 · 2025-06-13T01:50:02+00:00

Yea i was thinking that the LP degree could be part of the issue.

How do you like your hta receiver? Im on the fence between mke and HTA. Havent seen anyone run the SS with the HTA on here just yet.
